Do Europeans Use Transit a Lot? Perhaps, but Only in the Central City.

Recently I stumbled on an analysis of commutes in the second largest city in Germany, Hamburg. It's an old and interesting city that I had the chance to visit it in the late 1980s when there were two Germanys, West with capital Bonn, and East with capital (half of) Berlin.

Germany is a country with substantial use of rail both in and between cities. Hamburg is the second largest city in Germany. The county where Hamburg is situated has a population of about 1.8 million and the six surrounding suburban counties have a population of 1.5 million.

Unlike US cities which are characterized by very high (employment) density in the downtown and medium-to-low (population) density in areas surrounding the downtown, Hamburg and most old European cities have high (population and employment) densities over many acres. This makes the development of multiple rail lines meaningful and productive. Their rail lines are compact in length and are supplemented by bus or tram. As a result, transit use is moderate.

Their suburbs have a low use of transit. Let's look at the shares in the image below.

In the city of Hamburg, 33% use car modes, 19% use transit and 38% walk or bike. What's the largest difference between Europe and US. Is it transit use? No! It's Walk and Bike.

Walking and biking to/from work is more than 35% in Europe and less than 5% in the US.

In the suburbs of Hamburg transit drops to 7%. TheBus in Honolulu has a 6% share. Again the main difference is that even in the suburbs Europeans do a lot by walking and biking: 28% compared to less than 2% in US suburbs.

Some dense American cities like Honolulu look a lot like old European city suburbs. Like in Europe, the share of transit in the suburbs is rarely if ever over 10%. Investing on rail transit in suburban Europe or US cities is a poor decision both financially and for transportation productivity.

Brief Information about Panos

Panos D. Prevedouros, Ph.D. is a professor of traffic and transportation engineering at the Department of Civil Engineering, Univ. of Hawaii-Manoa since 1990.
Panos graduated from the Aristotle Univ. of Greece in 1984, and with Masters and PhD degrees in 1990 from Northwestern Univ. (Evanston, IL), a leading academic institution in engineering and transportation.
He chairs the Freeway Simulation Subcommittee of the Transportation Research Board. He was president of the Hawaii Highway Users Alliance from 2006 to 2008.
Panos co-authored a Transportation Engineering textbook and over 100 reports and technical papers. He received the 2005 Van Wagoner Award of the Institute of Transportation Engineers.
He co-organized the 1st International Symposium on Freeway Operations (ISFO) in Athens, Greece, and the 2nd ISFO in Honolulu in June 2009.
Dr. Prevedouros served in the Transit Advisory Task Force in 2006 and in the Technology Selection Expert Panel in 2008 of the City Council of Honolulu.
He run for mayor of Honolulu in the 2008 elections and finished 3rd in the primary elections with 18% of the vote from a field of nine candidates.
